The long holiday weekend will be full of summer-like weather. Subtropical Storm Beryl will ruin outdoor plans across the Southeast, while large stretches of the Plains and U.S. Northern-Tier contend with downpours and fresh thunderstorms. For good measure, high heat and humidity will build even more in the Central and Eastern U.S.

Today:The weather headlines will be focused on the Southeast, where Beryl will push onshore tonight. Though 3 to 6 inches of rainfall will ease existing drought concerns, tropical storm force wind gusts will damper the mood for outdoor barbecues from South Carolina to central Florida. Even those heading to the beach for sight-seeing will need to stay out of the water, as dangerous rip currents and immediate coastal flooding will be a certainty.Much like Saturday, much of the Central and Northern Plains will be caught in the severe weather danger zone. While downpours will pivot across Montana and the Dakotas, the same luck won`t be extended to residents from the Texas Panhandle to northern Minnesota and western Wisconsin. Here, powerful thunderstorms will explode and rumble across the landscape, with everything from high winds and very large hail to a few strong tornadoes possible. The Desert Southwest, Texas Plains, and much of the Mississippi Valley eastward to the Mid-Atlantic will boast the best weather across the Lower 48 states today. Though there will be a few hit-or-miss storms over the Mid-Atlantic and Carolinas, the main weather story will be the distinct contrast between the eastern U.S. heat and western U.S. chill.The mercury will soar into the 80s and 90s throughout the Central and Eastern U.S., while 50s and 60s cover the West. Only the Desert Southwest and interior California will see highs reach the 70s and 80s. Memorial Day:Subtropical Storm Beryl will still be peppering the Southeastern U.S. and Florida with downpours, ruining even more outdoor plans. Even outside of Beryl, much of the U.S. east of the Mississippi River will be contending with scattered showers and thunderstorms. Of note, the strongest will form ahead of a cold front from Texas to Michigan`s Upper Peninsula, packing a punch with large hail, damaging winds and even a tornado or two.Outside of a few nuisance U.S. Northern-Tier showers, and thunderstorms patrolling the Northwest into the Upper Midwest, the rest of the contiguous U.S. will enjoy a stellar end to the extended holiday weekend. Bright May sunshine will produce warmer temperatures across the western U.S., while the eastern U.S. stays steamy. Temperatures will range from the 50s and 60s across the northern High Plains and New England, to the lower and middle 90s along the U.S. Southern-Tier.Be sure to keep WeatherBug active to receive the latest weather in your neighborhood and get the latest updates anywhere on Twitter.What do you think of this story?Click here for comments or suggestions.
